Meddelelser 2010

20. december 2010: The closure of the IYA2009 Secretariat marks the end of the largest project that the International Astronomical Union (IAU) has ever embarked upon. In July 2007, the International Astronomical Union (IAU) established the IYA2009 Secretariat at the European Southern Observatory’s (ESO) Headquarters in Garching, Germany. The Secretariat’s role was to act as a hub for IYA2009 activities. It coordinated projects from the planning stages through to evaluation, and was a central contact and resource centre for the hundreds of national nodes, international organisations, global projects, the media and the general public. The Secretariat was embedded in ESO’s education and Public Outreach Department, which provided invaluable support and expertise for IYA2009. The IYA2009 was a huge success, involving 148 countries around the world organising hundreds of thousands of individual activities reaching hundreds of millions of people. Feedback has been extremely positive. The impact of IYA2009 on the scientific literacy of the ...

17. december 2010: The Space Telescope European Coordinating Facility, a unique collaboration between the European Space Agency (ESA) and the European Southern Observatory, will close on 31 December 2010 after 26 years. ESA’s continuing partnership with NASA on the Hubble mission ensures that European astronomers will continue to have access to observing time. The Space Telescope European Coordinating Facility (ST-ECF), the scientific and technical co-ordination centre for the Hubble Space Telescope in Europe, will close its doors at the end of December 2010. This is part of a process in which the European Space Agency is streamlining its operations and concentrating astronomical operations, archiving and data reduction expertise at its European Space Astronomy Centre (ESAC) in Spain. The ST-ECF was formed in 1984, six years before Hubble’s launch, as a key plank in ESA’s partnership with NASA and as a vital element in maximising Europe’s scientific return in the pre-internet age. Rather than ...

16. december 2010: Gamma-ray bursts are the most powerful explosions in the Universe and are thought to follow cataclysmic events, such as the collapse of a massive star. But to observe these fleeting events, astronomers need to be lightning quick. In this episode of the ESOcast, Dr. J explains how the VLT’s Rapid Response Mode makes it possible to observe gamma-ray bursts within minutes of detection by space-based telescopes. More episodes of the ESOcast are also available. Credits Visual design and editing: Martin Kornmesser and Luis Calçada. Editing: Herbert Zodet.

15. december 2010: The world’s most sensitive receiver for radio waves with wavelengths around 1.5 millimetres has been delivered to ESO. Its final destination is the Atacama Large Millimeter/submillimeter Array (ALMA), which is under construction 5000 metres above sea level in northern Chile, on the Chajnantor plateau. ALMA, the largest astronomical project in existence, is a partnership of Europe, North America and East Asia in cooperation with the Republic of Chile, and ESO is the European partner in ALMA. The receiver — operating in a wavelength range known as Band 5 at ALMA — will allow scientists to trace water vapour in the nearby Universe, and will also provide an unprecedented view of the most distant galaxies. The delivery is an important milestone for the project for ALMA Enhancement of Early Science, funded by the 6th Framework Programme of the European Commission. The project has developed new technologies from scratch in just five ...

Science in School is published by EIROforum, a collaboration between eight European intergovernmental scientific research organisations, of which ESO is a member. The journal addresses science teaching both across Europe and across disciplines: highlighting the best in teaching and cutting-edge research.

8. december 2010: Click here for a special seasonal greeting from everyone at the European Southern Observatory! This year has heralded many new discoveries, facilitated by the ESO telescopes, including the thought-provoking find of a distant planetary system that resembles the Solar System. Using the HARPS spectrograph attached to ESO’s 3.6-metre telescope at La Silla in Chile, astronomers detected up to seven planets in orbit around a Sun-like star (eso1035). And an unusual interloper — an exoplanet that entered the Milky Way from another galaxy — was found by a European team of astronomers using the MPG/ESO 2.2-metre telescope at La Silla (eso1045). In 2010 astronomers went far beyond just discovering such distant worlds. Amongst many new findings, astronomers used ESO’s Very Large Telescope at the Paranal Observatory in the Atacama Desert, Chile, to detect the first spectrum of an exoplanet (eso1002) directly and to analyse, for the first time, the atmosphere of ...

2. december 2010: The Universe contains a dark secret: most of the matter, whose presence is revealed by its gravitational effect, does not emit or absorb any light. Today, we have good reasons to assume this “dark matter” is made of a new type of elementary particle that interacts only very weakly with the light and with ordinary matter. For the past 25 years, we have explored different strategies to bring light into this darkness, and to elucidate the physical nature of dark matter. During the next Café & Kosmos, Dr. Georg Raffelt (Max-Planck Institute for Physics) will explain the justifications for the existence of dark matter, mention candidates from particle physics, and discuss possible strategies to search experimentally for dark matter. The Café & Kosmos series of discussions is organised jointly by ESO, the Excellence Cluster Universe and the Max-Planck Institutes for Physics, Astrophysics and Extraterrestrial Physics. The discussions take place on ...

2. december 2010: Professor Adriaan Blaauw, the European Southern Observatory’s second Director General, and a key figure in ESO’s early history, died yesterday, 1 December 2010, at the age of 96. “Adriaan Blaauw was one of the most influential astronomers of the twentieth century. I had the privilege to be amongst his students when he returned to Leiden from his position as Director General. He continued to remain keenly interested in everything to do with ESO, and still had his characteristic twinkle in the eye when he visited La Silla and Paranal earlier this year. It is hard to grasp that he is no longer with us,” said ESO’s current Director General, Professor Tim de Zeeuw. Adriaan Blaauw was born in Amsterdam, the Netherlands, in 1914. He studied astronomy at Leiden University, under de Sitter, Hertzsprung and Oort, and obtained his doctorate with van Rhijn at the Kapteyn Laboratory in Groningen in 1946, ...

26. november 2010: The brochure, called the International Year of Astronomy 2009 Final Report Executive Summary, offers an overview of the many events that took place during the Year, as detailed in full in the 1450-page IYA2009 Final Report, which was released earlier this year. “Tens of thousands of events were held during IYA2009, but unfortunately there is only space in this Executive Summary to mention a small handful,” says Catherine Cesarsky, chair of the IYA2009 Working Group, and the IAU President for most of IYA2009. “We’ve included a diverse cross-section of events that are representative of the Year, but they should not be viewed as a ‘best of IYA2009’. We are grateful to everyone who took part in IYA2009 and we would like to say thank you to you all." The print-ready files and source files (Adobe InDesign file and images) are also available for IYA2009 stakeholders to adapt for use in ...

23. november 2010: The growing and prolific community of photographers of the night sky in Chile will gather at the first Southern Astrophotography Conference (Congreso Austral de Astrofotografía, CAA), to be held on the ESO premises in Santiago, on 26–27 November 2010. This event — supported by ESO, Universidad Diego Portales and ACHAYA (Chilean Association of Astronomy and Astronautics) — aims to become an inspiration for the region. It includes as keynote speakers, the ESO Photo Ambassador Stephane Guisard, the Belgium astrophotographer Daniel Verschatse and the Chilean astrophotographers Joaquín Pérez and Guillermo Yáñez, among others. But not only professionals and seasoned amateurs are invited to attend. Enthusiastic beginners equipped with just a digital camera can discover simple techniques to capture the majesty of our cosmos. The general public will also have the opportunity to meet senior astrophotographers during an open session on Friday, 26 November. This open session is free of charge and ...

23. november 2010: An international team of astronomers has used ESO telescopes and other facilities to discover and study a unique and exotic star system comprised of a very cool, methane-rich (or T-) dwarf star and a “dead” white dwarf star in orbit around each other. The system is a “Rosetta Stone” for T-dwarf stars, giving scientists a way of finding the mass and age of this old methane dwarf. The team, led by Dr Avril Day-Jones of the Universidad de Chile and composed of astronomers from the University of Hertfordshire (UK), and the University of Montreal (Canada), is publishing its results in the journal Monthly Notices of the Royal Astronomical Society. The system is the first of its type to be found. Methane is a fragile molecule destroyed at warmer temperatures, so is only seen in very cool stars and giant planets like Jupiter. Neither giant planets nor T-dwarf stars are massive ...

19. november 2010: Version 2.0 of the ESO Virtual Tours brings higher quality views of the ESO facilities in Chile, as well as more background information incorporated through web links and pictures, allowing everyone to explore the sites of the most productive observatory in the world.

Further information will be provided to the accredited reporters.

8. november 2010: At the autumn 2010 Council Meeting of the EIROforum, a partnership of seven European Research Organisations — including ESO — with large research infrastructures, the Directors General unanimously accepted the European X-ray Free-Electron Laser (XFEL), based in Hamburg, to become its eighth member. The European XFEL is an international research facility that will use ultra-short X-ray flashes to map the atomic details of viruses, decipher the molecular composition of cells, take three-dimensional images of the nano-world, film chemical reactions and study processes such as those occurring deep inside planets. XFEL is currently under construction, with commissioning being planned for 2014.

5. november 2010: The Santiago Central Office headquarters of the Atacama Large Millimeter/submillimeter Array (ALMA) project have been officially handed over in the Vitacura district of the Chilean capital. Construction of the new building, which is adjacent to ESO’s Santiago offices and was built by ESO as part of its responsibilities as the European ALMA partner, has been completed. The handover ceremony took place on 5 November 2010. The ceremony was attended by the ESO Director General, Tim de Zeeuw, and the ALMA Director, Thijs de Graauw. The new building has a size of almost 7000 square metres over two storeys. It has more than 100 offices, as well as other facilities such as meeting rooms, an auditorium, and underground parking for 130 cars. The underground parking will allow some of the previous above-ground parking spaces to be replaced with green areas. As part of the construction, fourteen trees already on the site ...
